Matplotlib colormaps from the yt project !

## Colormaps overview

The following colormaps, as well as their respective reversed (`*_r`) versions are available

### Perceptually uniform sequential colormaps



    



### Monochromatic sequential colormaps



    



### Miscellaneous



    



## Installation

with `pip`

```shell

python -m pip install cmyt

```

or with `conda`

```shell

conda install -c conda-forge cmyt

```

## Usage

cmyt integrates with matplotlib in a similar fashion to

[cmocean](https://matplotlib.org/cmocean/) or

[cmasher](https://cmasher.readthedocs.io)

```python

import numpy as np

import matplotlib.pyplot as plt

import cmyt  # that's it !

# generate example data

prng = np.random.RandomState(0x4D3D3D3)

noise = prng.random_sample((100, 100))

x, y = np.mgrid[-50:50, -50:50]

z = 5 * np.exp(-(x**2 + y**2) / 1000)

# setup the figure

fig, ax = plt.subplots()

ax.set(aspect="equal")

# now we can refer to cmyt colormaps as strings

im = ax.pcolormesh(x, y, z + noise, cmap="cmyt.arbre", shading="flat")

fig.colorbar(im, ax=ax)

```



    



```python

# alternatively, cmyt maps can also be imported as objects

from cmyt import pastel

fig, ax = plt.subplots()

ax.set(aspect="equal")

im = ax.contourf(x, y, z + noise, cmap=pastel)

fig.colorbar(im, ax=ax)

```



    



A gallery of comparable examples using all colormaps from cmyt is available [in the test directory](https://github.com/yt-project/cmyt/tree/main/tests/baseline).
